Hi again,
Finally I managed to repair my CD to read disks again, the problem was mechanical, applying some pressure on the loading mechanism made the RT4 read disks again. Used the time it is still working to successfully update to v. 8.31.1.R1 after burned a CD with ImgBurn, tried before with another burn software, didn't work. Couldn't buy here the original CD from Peugeot/Citroen for 5 cents (it is 10 euros from private sellers) it took me around 40 min and the update was successful, now my question is How to put the good looking theme with the old Citroen 2CV on my RT4? I looked on the net but couldn't find instructions , found only the themes.

Thanks Bricoman,
I've updated the software to 8.31 my problem was to unlock the USB, I've wasted 10 CDs trying to burn the Mirascript, didn't know that it can be run from the USB pen directly and I haven't well connected the plug on the back on my RT4. After all connections checked the script runs from the USB directly and the unlock of the USB function was successful. Tomorrow I will try to update the maps as I have the original version of 2007/2008.
THANKS FOR THE HELP.
